TELEPHONIE-LOCK.

' SPECIFICATION forming part of Letters atent 1N o. 728,994, d

To lf/ZZl whom, it T11/(ty concern;

` Be it known that I, WILLIAM H. SCOTT, a citizen ofthe United States,residing at St. Louialllissouri, `have invented a certain new and usefulImprovement in Telephone-Locks,

of which thefollowing is a full, clear, and eX-` Vact description, Suchas will enable others skilled in the `art to which it appertainsto makeand use the same, reference being had 1o to the accompanying drawings,forming part of this sp'ecication, in which j Figure 1 is an elevationthrough-the lbox or casing, said casing being Shown in section. In thisligure the parts are shownin full lines in their normal locked position.The heavy dotted lines indicate the positions of a deposited coin andthe pivoted locking-dog after the coin has been deposited and before theslide-bar has been elevated, and the light 2o dotted lines indicate thepositions of the parts after the slide-bar has been elevated. Fig. 2 isa plan view, a portion of the casing being shown in section.

My invention relates to improvelnents in z5 telephone-locks, my objectbeing to provide a simple and efficient construction having but fewparts.

To this end, and also to improve generally upon devices of the characterindicated, my

5o invention consists in the various matters hereinafter described andclaimed.

Referring now more particularly to the drawings, 1 represents a portionot' a telephone-box, which can be of any suitable con- ;5 struction, and2 indicates the customary suspension-hook for the usualtelephone-receiver 3. A box or casing 4 is secured to the wall or othersupport to extend at the side of the telephone-box and over the saidsuspen- Ic sion-hook, said casing containing the hereinafter-describedlookin g mechanism and being provided with a coin-raceway 5 and alsowith a horizontal slot 6 in its bottom wall, suitable guides 7 beingproperly related to the L5 said slot to direct the slide-bar in itsmovements. Movable through said slot and between said guides is asubstantially vertical slide-bar 8, whose lower end lies above thereceiverl suspension-hook; 2 and locks said go hook in its lowermostposition for well-un- 'A `Application led June 25,1902.Serialllo..113.113.` (No model.)

derstoodpurposes, said slide-bar being preferably provided with a Slot9, which receives a guide-pin 10, extending upon the casing.. Pivotedabove the slide-bar is a locking-dog l2, whose lower surface normallyAlies above the upper end 11 of the slide-bar in such position that saidSlide-bar is normally locked Vagainst upward movement, said locking-dogIpreferably being provided a projection 13, which is adapted to engagethe edge of the slide-bar, and thus prevent the locking-dog fromswinging beyond its proper position. The end of the lower wall 14 of theraceway 5 is spaced from the upper edge of the slidebar, so that acoin-seat is formed between said parts, and in its side toward theraceway the slide-bar is provided with a recess 15, which when theslide-bar is in elevated position cooperates with the raceway to producea coin-passage into the coin-receptacle 16. The upper portion of theedge of the slidebar opposite the raceway is inclined inwardly andupwardly, as shown at 17, and the surface of the locking-dog with whichsaid inclined portion of the slide-bar engages is out away, as shown at18, in order to permit the proper movement of the parts without throwingthe locking-dog through an unduly large are of a circle.

The parts normally lie in the positions indicated by full lines in Fig.l, the receiver suspension-hook being locked in lowermost position in amanner which will be apparent. Upon the introduction of a coin or tokeninto the raceway Such coin falls into the seat between the end of thewall 14 and the end of the slide-bar, and as it falls into such posi'-ti on it engages the lockingdog and throws the same out of lockingposition. The slidebar is now free to be moved, and as soon as thereceiver is lifted from the suspensionhook the usual spring connected tosaid hook raises the same, and thus carries the slide-bar upwardly. Inits upward movement the slidebar throws the locking-dog into theposition indicated by the light dotted lines and forces the coinbackwardly along the raceway until the recess 15 reaches such positionwith relation tothe raceway that the hereinbeforementioned passage intothe coin-receptacle is IOO produced, when the coin falls through thepassage into said receptacle. The parts remain in the positions shown bythe light dotted lines until the receiver is again placed on thesuspension-hook, when the slide-bar falls in a well-understood mannerand the lockingdog swings downwardly and forwardly into lockingposition, undue movement of the dog toward such position being preventedby the engagement of the projection or finger 13 with the slide-bar. Thelocking-dog lies intermediate the slide-bar and the pivot pin or stop19, thus eiectually locking the slide-bar against upward movement untilanother coin is deposited.

I am aware that many minor changes in the construction, arrangement,and,- combination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

The locking-dog is pivoted at such a point with relation to the upperend ofthe slidebar that there is less space between said bar end and thepivotal member than is the width of the operating-coin, whereby themovement of said coin toward said locking-dog is limited and there is nopossibility of 1said coin falling over the end of the bar in suchposition that the bar cannot operate or kthe coin be properly dischargedinto the coin-receptacle.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a mechanism of the character indicated, a substantially verticallymovable lockingbar, a lockin g-dog pivoted above said bar and adapted tohang in the path of upward movement of said bar to prevent such'movement thereof, and a coin-raceway wall spaced from one side of saidbar a distance less than the width of an actuating-coin and adapted todirect a deposited coin against said dog and upon the top of said bar,whereby a coin-seat is produced between the end of said'wall and theupper end of said bar, said bar having a cut-away portion upon its sidetoward said wall and below said coin-seat, whereby a deposited coinmoves said locking-dog from locking position, seats upon said seat andfalls therefrom upon upward movement of said bar; substantially asdescribed.

In testimony whereof I hereunto aflix my signature, in the presence oftwo witnesses, this 21st day of June, 1902.
